Fourth seeded Sharapova's powder-blue, dress described as "empire line", resembled a nightdress. In fact, it took the commentators by surprise, prompting one to say the Russian ace needn't change after her late night match against Ashley Harkelroad, which she won quite easily, and could go straight to bed.
Karolina Sprem sported a similar 'nightie' in lavender, though it failed to inspire her against top seed Lindsay Davenport.
India's tennis sensation Sania Mirza turned up in an all-black two piece, while the Williams sisters also made a strong fashion statement with their colourful outfits.
Serbia and Montenegro's Ana Ivanovic, who topped Sharapova in a tennis fans' poll of 'sexy' players, also looked sizzling hot in red.
